Liam Neeson, celebrating his 60th birthday, isn’t fussy when it comes to restrooms. The Irish actor, while being toasted at a dinner by friends at the Waverly Inn on Thursday, opted to use the ladies’ loo instead of waiting for the men’s to become free. But his visit gave some female diners a very pleasant surprise. “You’ll never guess who’s in the ladies’ room,” a woman standing on line excitedly whispered to another, sharing that it was indeed Neeson. When he finally emerged, he was as pleasant as ever, apologizing to the line of women waiting: “I’m so sorry. Please excuse me.” He even held the door open for the first lady to walk in, witnesses said. “You can use my bathroom anytime,” one guest was overheard telling the tall, handsome actor. Neeson was at the posh spot for a private birthday dinner with 40 guests.
